The remote MCP endpoint at api.awesomevideoeditor.com/mcp supports Streamable HTTP and content negotiation, with a keyless path that grants welcome credits once per network and pricing at 5 credits per audio minute, plus 2 for translation. An importable n8n workflow using core nodes is also offered for automation.", "body_md": "I'm the maker of [AwesomeVideo](https://awesomevideoeditor.com) — a hosted captions MCP + REST API that returns a burned-in MP4 plus SRT/VTT.\n\nIf your agent can call tools, you can caption a sample clip without creating an account first. Point the client at the keyless endpoint and use three tools.\n\nRemote MCP URL:\n\n`https://api.awesomevideoeditor.com/mcp`\n\nDocs / Cursor / Claude recipes: [awesomevideoeditor.com/mcp](https://awesomevideoeditor.com/mcp)\n\nMany clients that only speak JSON on `initialize` / `tools/list` work against this endpoint (Streamable HTTP + content negotiation).\n\nCall `create_key` (or use the anonymous REST path). You get welcome credits once per network — enough to try a short clip. No email wall for the agent path.\n\nCall `caption_video` with a public MP4 URL. Live sample we keep online:\n\n`https://awesomevideoeditor.com/samples/cc0-interview-es.mp4`\n\nYou get back job status, then downloadable MP4 (styled burn-in) + SRT/VTT/JSON transcript. Pricing is live at `/v1/pricing` (currently 5 credits per audio minute for captions; +2 with translate).\n\nIf you automate in n8n instead of an agent, there is an importable workflow (core nodes only, no key baked in):\n\nMost caption SaaS is UI-first. Agents need: a tool list, a key they can mint, and a real video URL that is not `example.com`.
